Last week, I mentioned the loud click noise the trackpad made on my new late 2008 MacBook Pro. I even posted a video comparing the sound to an older, quieter model. Today, I think I may have found a solution.

On YouTube, a user commented on my video and mentioned how stuffing paper between the trackpad and battery could dampen the clicking noise. After trying this, I found that I could reduce the loudness of the click, but at the expense of stiffening the clicking mechanism; it’s actually quite difficult finding the perfect balance between click noise and click resistance.

My solution uses layered pieces of Kleenex that are sized to cover the underside of the trackpad, directly underneath the battery (no tools required). It’s something that takes a bit of trial and error, as you’ll need to put the battery and case cover back in place each time to accurately test any changes that you’ve made.

In the end, I settled with around 6 squares of Kleenex to made the click quieter than my early 2008 model MacBook Pro. The resistance to depress the click pad has been increased a tad, but it’s nothing my thumb can’t handle. So long as the paper doesn’t catch on fire (let’s hope your battery never hits 451 F), this fix has tackled one of my biggest gripes with Apple’s new unibody laptops.

In the future, I want to use some proper sound proofing material to see if I can further quiet the trackpad without increasing click resistance. I’m sure there are better materials to use other than toilette tissue, but right now, this is a very cheap and easy solution to try. Give it a shot and let me know how it goes.

UPDATE: I now have a video showing the procedure.
